As you've probably heard, Mary-Kate Olsen recently got engaged to her long-time beau, French banker Olivier Sarkozy, and the ring that he gave her is pretty spectacular. Not surprisingly, the paparazzi were able to snap 27-year-old Olsen wearing the piece in both New York and Paris (where she attended the Louis Vuitton fall 2014 show) this week, and thanks to some good ol' Internet sleuthing, details about her ring are beginning to emerge.
According to PopSugar Fashion, Olsen's new jewel is a vintage gold, 4-carat diamond and sapphire ring by Cartier that was sold at auction at Sotheby's for a whopping $81,250, more than $20,000 more than it was projected to sell for. This might seem like a steep price to pay for an engagement ring, but let's take a moment to remember that Olsen and her twin sister Ashley did design a $34,000 alligator backpack for The Row not too many seasons ago.
The ring dates back to 1953, and was purchased in New York on Feb. 6. A rep for Cartier was unable to comment on whether Olsen's ring is, in fact, this exact vintage Cartier, but either way, it's stunning.
